ok you go out and spend lets say $4000 on a FULL gsr Swap which is the most common swap. and get about 140-145 WHP

Now you can take say a JDM D15b ($800) for full swap. throw pistons,rods, and a crower stg 2 kit, ($1000) and a decent header and aftermarket intake manifold ($800).and be making around 140-150 whp with good tuning. and prolly save $1000. im definetely not putting down DOHC There a great motor but in (MY OPINION). you can make a SOHC just as fast and spend the same amoutn of money. and have better gas mileage.

But like i said if you want to just swap a motor and not do any internal work. and be quick go with a DOHC.

everything you said is true but your spending a decient amount of money to equal a STOCK B series. gas milege is more dependant on the quality of the tune and how heavy your foot is.

yea i understand that im just saying money wise u can make a SOHC just as powerful as a DOHC but in my opinion a SOHC would be more reliable. but like i said before if you arent into doing work for power then definetly swap the DOHC and be done with it. me i like to get power by building.

but very true with the gas mileage and a heavy foot +1

SOHC is the way to go cheaper lighter and can be just as fast.And last but not least you dont have to sell one of your balls to buy a DOHC swap.

Seriously, how many SOHC motors have you seen make 300whp on 8psi?
I agree.... and on top of that you have two cams/cam gears (time settings) to play with so you can have the better on both end of things...
